Like with many other doctrines, the doctrine of the kingdom in the New Testament builds on the concepts already revealed in the Old Testament.
New Testament doctrines is the study of what God has revealed about Himself in the New Testament. The system of New Testament theology takes the various truths that the New Testament books teach us about God and presents them in an organized fashion. The New Testament discloses the coming of the Messiah predicted in the Old Testament, the rejection of the Messiah by Israel, the fulfillment of the Law, the birth of the New Testament church (the body of Christ), the church age, the gospel of Jesus Christ, and instructions for believers in Jesus Christ
